CYCLOMMATüS PASTEURI. 235 



The under surface of the head and the sterna are densely 

 and finely granulated , the abdomen and femora shallowly 

 punctured , each puncture bearing a narrow white scale. 

 The prosternum is keeled along the middle , and the inter- 

 coxal part strongly elevated and, posteriorly, compressed. 

 The metasternum has, just behind each intermediate coxa , 

 an excavation , which excavations are separated by the 

 raised anterior portion of the central line. 



The fore-tibiae are straight , not very elongate , and 

 without any spine on the outside. 



The described male-specimen , a representative of the 

 forma maxima, originates from Padang Sidempoean (Tapa- 

 noeli Residency : West Sumatra) and has been offered last 

 year to the Leyden Museum , together with other very 

 interesting beetles from the same locality , by Mr. J. D. 

 Pasteur, whose name I have much pleasure in associating 

 with this conspicuous species. 



Cyclommatus eanaliculatus , n. sp. cT, Q. 



Likewise a very interesting species and easily recognizable 

 by the very distinct median groove on the pronotum , which 

 groove becomes deeper towards the base in consequence 

 of the raising margins. Moreover the outer upper margin 

 of the mandibles is notched at some distance from the tip 

 so as to form here a small tooth. 



Length of a male of the forma maxima 50 mm., 

 breadth at the shoulders 1 1 mm. — Dark red-brown , with 

 faint tinges of metallic green and purple, the margins of 

 the mandibles and of the prothorax, the front-margin of 

 the head and the outer margin of the elytra blackish ; the 

 antennae and tarsi pitchy black, the upper side of the 

 femora pale yellowish brown. 



The whole insect is sparsely (from abrasion ?) covered 

 with small ovate dirty grey scales; the tarsi are glabrous 

 with the exception of the under surface which is densely 

 covered with pale ferruginous hairs.
